The duality is present only when form, time and space are present.

Realization of the ultimate truth or Brahman is possible on this very life itself. The highly evolved seeker, who has an intense urge, and sharpness to grasp non-dualistic or Advaitic truth, is fit to realize the ultimate truth or Brahman.

One who has realized ultimate truth or Brahman, is freed from experiencing the duality as reality. He is a Gnani. A Gnani is liberated from the ignorance, which is the cause of the duality. Thus a Gnani is freed from experiencing the form, time and space as a reality while still living in the practical world. He continues to live in the practical world in self-awareness.

The ignorance is burnt in the Self ~awareness. The waking entity along with the waking experience eventually dies, and a Gnani is said to have attained Moksha before his physical death. Thus he is free from the concept of the cycle of the experience of the birth, life and death.~Santthosh Kumaar

The duality is present only when form, time and space are present. The form, time and space are one in essence. The ego, body and the world are one in essence. That essence is consciousness.

Thus there is no division in consciousness in reality. The thinker, thought, and the world are one in essence (soul or consciousness). The one who has realized the soul is the true self will not see the illusory division even though he is in the midst of duality.

A Gnani is fully aware of the fact that, his body, his ego and his experience of the world are mere mirage created out of consciousness whereas the ignorant thinks that, the experience of the birth, life, death and the world as reality. Because ignorant bases himself on the waking entity (ego), which is the false self within the false experience (waking).

So long as one is in the realm of duality, one has to explain how or why one thing came from another, and contradictory views are expressed. But when a Gnani shows there is no second, there is no production, and the contradictions do not arise at all, when the ultimate thing is consciousness alone. Thus consciousness is ultimate truth or Brahman.

The dualists’ arguments are based on the false self (ego or the waking entity) and false experience (mind or waking or dream or universe) To show the weakness of the position of dualistic view point. They at their wits end to explain.

Existence cannot be a cause and effect at the same time, from the point of view of the dualists, but deeper self-search shows the Existent is no-two, and the causality can’t rise at all. Dualistic theory says that whatever was in the cause was also in the effect. They say that the gold brick, the gold medal, the gold ornaments --are in the seed--the gold. Deeper self-search reveals the fact that, if cause and effect are one what is the difference between the two?

The logic holds good for the practical purpose in the practical life (waking). Soul-centric reasoning leads to non- dualistic self-awareness.
